Snap-N-Seal® F connectors, model
DXE-SNS6-25
which contains 25 connectors; enough for the
entire array plus spares. Snap-N-Seal® connectors cannot be installed with normal crimping tools or
pliers. The
DXE-SNS-CT1
Compression Tool for Snap-N-Seal® 75Ω Coax Connectors is an
essential tool for proper connector installation.
Lightly coat threads of F connectors with
pure clear non-hardening silicon dielectric compound
,
such as
PTX-22058
Permatex Dielectric Grease, to improve reliability of electrical connectors. This
will lubricate threads, seal connector threads from water ingress, and reduce chances of unwanted
bonding or welding of connector threads.
If dielectric grease is not used, the potential for damage
to the various connectors may result and is not covered under warranty.
Note:
DO NOT
use pliers or other tools to excessively tighten the type F connectors; they
do not require high torque to make a good connection.
F connectors are very
reliable strong connectors for their size, but carelessness can damage them.
Excessive tightening torque can loosen the chassis mounting-nut, allowing the
connector body to rotate and fracture the mounting tabs on either installation or
removal of the connector. F-connectors require modest torque, typically 6-12 inch-
pounds. 20-30 inch-pounds are FAR too high. That value, although commonly used,
is just wrong.
Damage to the various connectors may result and is not covered
under warranty.
Use a tool such as the
DXE-CIT-1
F Connector Tightening Tool.
Additional weatherproofing protection can be provided when using the
PTX-22058
Permatex Dielectric Grease on all coaxial connections. Dielectric grease is ideal for
keeping moisture from entering your coaxial connectors. It also acts as a lubricant
allowing easy connector removal by stopping corrosion of electrical connectors.
Vertical Element Feedlines
Use 75Ω coaxial cable from each antenna element to the
RCA8C-1
. The eight feedlines from the
RCA8C-1
to the
elements can be any length needed to accommodate the size of
the array,
but must all be the same physical length, velocity
factor and type
. Note the orientation and numbering of the
elements by using
Figure 7
.
Be sure the appropriate antenna
element is connected to the proper
ANT
connector on the
RCA8C-1
.
